Alien Metals Limited (LON:UFO), a minerals exploration and development company, has noted that GreenTech Metals Limited (ASX: GRE) has announced the findings of an independent geochemical review of the Munni Munni PGE-Cu-Ni Project, conducted by Dr Scott Halley, a specialist geochemist with experience in magmatic sulphide systems and layered mafic-ultramafic intrusions. Dr Halley’s review has provided a new and compelling framework for understanding the broader untested potential of the Munni Munni intrusive complex, identifying discrete high-priority exploration targets around the base of the intrusion and interpreting the key controls on Cu-Ni-PGE sulphide mineralisation.
Key Highlights:
| · | Soil geochemistry demonstrates discrete copper anomalism over the base of the ultramafic sequence, indicating the basal contact of the Munni Munni intrusion is prospective for basal contact-associated Cu-Ni+/-PGE mineralisation |
| · | The ultramafic lower section of the intrusion has a widespread depleted copper signature indicative of segregation of magmatic sulphides, consistent with basal sulphide accumulation |
| · | Major element and trace element systematics map out the fractionation processes in the Munni Munni intrusion. The Ferguson Lode is just below the transition from ultramafic to gabbroic rocks, like most other PGE systems, including the Bushveld Layered Intrusive Complex. |
| · | A ~5km x 2km strong copper anomaly associated with elevated vanadium and titanium values in the upper sequence suggest magnetite rich zones with disseminated magmatic copper sulphides. |
